A therapeutic appliance includes an elongate central cushion, four elongate peripheral cushions and opposing seams for interconnecting sets of two of the peripheral cushions to each other and to opposing sides of the central cushion. In one embodiment, the central and peripheral cushions collectively form a generally X-shaped configuration when viewed in transverse cross-section. In another embodiment, the central cushion can be eliminated so that the axes of the peripheral cushions lie at the corners of a rectangle when viewed in transverse cross-section. Each of the peripheral cushions is preferably of cylindrical configuration so as to provide snug support of a limb of a patient therebetween and prevent slippage of the appliance away from the patient during sleep, etc. However, straps may also be attached between adjacent ones of the peripheral cushions, for providing additional support and immobilizing a limb, by biasing a pair of adjacent peripheral cushions towards each other and eliminating any likelihood of slippage of the appliance away from the patient.
